You can design and create a custom template definition file using a text editor with basic YAML validation. Start with the Creating Command Central Composite Templates tutorial, which walks your through the steps required to develop a basic template.

You can also use the sample templates from the https://github.com/SoftwareAG/sagdevops-templates project on github as a source template or example for creating custom templates. Read and follow the instructions in the readme file and wiki of the project and then select and modify the sample template that matches or is close to your requirements. Use the sample templates from https://github.com/SoftwareAG/sagdevops-templates to set up environments with Software AG products of release 10.1 and higher.
